[0099] Cell Migration Assay [0100] Cancer cells have tendency to migrate from primary site and metastasize at different tissues and organs which makes it more aggressive and uncontrollable. This assay has been performed to study effect of CH formulation on human breast cancer (MDA-MB-231) cell migration. [0101] To evaluate the effect of formulation 1 cell migration MDA-MB-231 cell line was used. Cells were incubated in 12 well plate to obtain uniform monolayer cell under standard growth conditions. Monolayer was scraped using sterile tip to create wound. Cells were treated with formulation 1 (1 to 6 μg/ml) and incubated for 24 hrs. Formulation 1 inhibited the cell migration by 85-90% at a concentration range 3-6 μg/ml. Observations and results are self-explanatory, as seen in the accompanying
[0102] Validation Study 5: Wound Healing Assay [0103] Method: Human breast cancer (MDA-MB-231) cell line obtained from American Type Culture Collection (ATCC, Manassas, Va., USA) and used for this assay. MDA-MB-231 cells were maintained in DMEM medium contains 10% FBS, penicillin (100 U/ml) and streptomycin (100 mg/ml) under humidified atmosphere at 37° C. MDA-MB-231 cells were seeded in a 12 well plate and incubated till uniform monolayer achieved. [0104] Sterile T-200 micropipette tip was used to scrape wound in order to make wound of constant width. Cellular debris was removed by DMEM basal medium followed by treatment of CH formulation (1 to 6 μg/ml) and incubated at 37° C. for 24 hrs. [0105] Migration of cells to the wounded area was observed by using phase contrast microscope (Nikon) and photographed (100× magnifications). Distance migrated was measured by image-Pro plus software. Percentage of wound closure was estimated by: Wound closure Percentage=[1−(wound area at Tt/wound area at T0)×100%, where, Tt is 16 hrs after wounding and T0 is the time immediately after wounding. [0106] Results: The results showed significant inhibition of migration of cells with increase in concentrations from 1-6 μg/ml, as shown in the accompanying
[0108] Validation Study 6: Delayed Type Hypersensitivity Assay in SRBC Immunized Rat Model [0109] Method: Wistar rats were treated with test drug and vehicle as described in the experimental protocol. After blood collection, rats were challenged by injection of SRBC (0.5×109 cells/ml/100 g) into the left hind foot pad. Isotonic saline was injected in right hind paw. Paw oedema was measured at 0 and 24 h after SRBCs challenge using digital plethysmometer (Ugobasile, Italy). The pre- and post-challenge difference in the thickness of footpad was expressed in millimeter and specific paw swelling (D %) was calculated which will be taken as a measure of DTH. [0110] Observation: The results of DTH assay showed that CH formulation significantly reduced the paw volume as compared to disease control group indicating an anti-inflammatory action on delayed type hypersensitivity. Effects of CH (CH) formulation on delayed type hypersensitivity assay in SRBC immunized rats can be seen from the accompanying
[0111] Validation Study 7: Cyclophosphamide Induced Immunosuppression in Mouse Model [0112] Method: Mice were subjected to immunosuppression by hypodermic injection of CPA (70 mg/kg/day) on days 4, 8 and 12 to establish the immunosuppressive animal model, while mice in normal control group was administered with the same volume of sterile physiological saline solution. The animals were treated with test drugs for 14 days. On 14 days, the animals were anesthetized and blood was collected by retro-orbital plexus for platelet count. [0113] Observation: The results showed that CH formulation increased the platelet count as compared to disease control group indicating immunostimulatory effect against cyclophosphamide. Effects of CH (CH) formulation on platelet count in cyclophosphamide suppressed mice can be seen from the accompanying
[0114] Validation Study 8: Carbon Clearance Test [0115] Method: A carbon clearance test were used to determine the phagocytic index, on day 14, 2 hours after the last administration, mice weighed and then injected with Indian ink (0.1 mL/10 g BW) via the tail vein. A 20 μL specimen of blood were collected from the retro-orbital plexus at 2 and10 min immediately after ink injection. Blood samples mixed with 2 mL of 0.1% Na.sub.2CO.sub.3 solution, and the absorbance measured at 650 nm. Afterwards, mice sacrificed by cervical dislocation. The spleen and liver were excised and immediately weighed. The rate of carbon clearance (K) and the phagocytic index (α) were calculated as follows:
[0118] Validation Study 9: TNF-α and IgG Assay [0119] Method: The levels of TNF-α and IgG in serum were analyzed by commercially available ELISA kit, according to the instructions of the manufacturer. The assay was performed by the solid phase sandwich ELISA by adding antigen and biotinylated polyclonal antibodies specific for TNF-α and IgG, to the microtiter plate wells. The plate well walls were precoated with polyclonal antibodies. The HRP conjugated streptoavidin was added and incubated. Further TMB substrate was added to produce the coloured reaction product. The enzyme reaction was stopped by using stop solution. The absorbance of the coloured product was measured using software based microplate reader (ECIL) at 450 nm. [0120] Results: The results showed that treatment with CH formulation increases the levels of TNF-α as compared to disease control indicating the immunostimulatory effect of CH formulation. Effects of CH formulation on TNF-α levels in cyclophosphamide suppressed mice can be seen in the accompanying
